This project uses git submodules, you will either need to use git clone --recursive <repourl> or after cloning use git submodule update --init.

The following packages must be installed: build-essential autoconf automake gperf texinfo help2man ncurses-dev bison flex libtool-bin libjson-c-dev libiberty-dev dfu-util

This has been tested in various GNU/Linux machines, in other platforms you might need more, and possibly differently named, packages.

This will build the toolchain and dependencies:

cd firmware
./build-deps.sh

To package the firmware for the Signet client GUI we need the firmware encoder: make signet-firmware-encoder.

make builds the Signet firmware.

Package it with: ./signet-firmware-encoder signet-fw.bin signet-fw.sfw

This will build the toolchain and dependencies:

cd firmware-hc
./signet-hc-build-deps.sh

To build the Signet High-capacity firmware encoder: make hc-firmware-encoder

Signet HC firmware has too parts, they need to be built separately: make BT_MODE=A and make BT_MODE=B.

To package Signet HC firmware, we need to specify the version number too: ./hc-firmware-encoder signet-fw-a.bin signet-fw-b.bin signet-fw-0.2.3.sfwhc 0 2 3

Both Signet and Signet High-capacity firmware uses locally compiled toolchains (via crosstool-ng) to increase the chance of reproducible builds.
